APPARATUS FOR THE MANUFACTURE OF HORN-LIKE MASSES FROM CASEIN,

Application filed FebruarylG, 1916,

To all whom it may concern:

Be it known that I, Dr. TELS, a sub'ect of the King of Prussia, residing at arburg-on-the-Elbe, 5 derstrasse 102, in'the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in A paratus for 1 the Manufacture of Horn-Like asses from Casein, of which the; following is a specifi-' cation.

This invention relates to improvements in apparatus for producing horn-like masses from casein by a'continuous process. The continuously fed granular slightly moistened casein is compressed in the rear portion of a cylindrical press under gradually increasing pressure, while being moved forward, and is then kneaded in an adjacent forward chamber that is provided with a heating apparatus, and the finished mass is pressed-out through the outlet that nozzle.

The apparatus according to the invention consists substantially of a screw press having. a c linder (that is cooled at the supply channe and heated at the kneading chamber) for receiving and compressing the granular casein into a plastic horn-like mass, and obstacles'that serve to produce a high pressure are arranged in the pressed string of mass. These obstacles or resistances serve also as kneading members. initial coolin the slightly moistened casein (to which co oring matters and filling matters are added if necessary) remains at first still granular, so that the aircan escape to the rear. For cooling and heating purposes the cylinder is provided with suitable jackets into which the cooling or heating fluid of the cylinder becomes gradually denser under high pressure and at the same time is kneaded energetically by the obstacles varranged in the kneading chamber.

7 It is advisable to make the thread of the vpressing screw with different pitches along the latter,,so that the pressure will increase gradually toward the end of the spindle, that is to say, toward the front endthe thread is closed and is more steeply inclined to the horizontal, so that the mass is com-' pressed to a greater degree.

Screw presses are known per se. This invention however consists not only in a completely new use, but alsoin a diiferent construction of such a press, such as the forms Specification of Letters Patent.

AMAisDUs BAR-' arate kneading cooling jacket d.

is fitted with a Owing to the is admitted. The mass in the heated portion' rotate with the latter.

of the screw of the cylinder and of a sepchamber which are requisite for producing the desired very high pressure.

The drawing shows the apparatus in longitudinal section. The screw spindle b is moved in the direction of the arrow in the cylinder a. Commercial mixedwith the added coloring matters and filling substances, is pressed from the charging-hopper c-by the motion of the. spindle, and

casein which con-- terms in all about 20 to 50 per cent. of water, and has been previously is compressed. The,

forward automatically casein remains granular at first owing to the medium flowing in the he forward portion of the cylinder at is provided with t e heating jacket 6. Under thev pressure and the heat the casein in this forward portion of the action of the coolin cylinder assumes a coheri-ng plastic consistency, and it is then pressed through'sievelike obstacles f, arranged in the extension g of the cylinder. These sieve-like obstacles serve as string of mass, and efiecting a most intimate mixing of the coloring matters and other admixtures with the casein and a perfectly homogeneous condition of the mass.

The mass then passes out from the outlet h (fitted with a nozzle) in a homogeneous horn-like condition. a For the purpose of producing the desired suificient high pressure, two sieve-like obstacles f, f are interposed whichserve also as kneading devices. In some cases only one of such obstacles will be suflicient. Also, according-to requirement, more than two such obstacles may be provided, and the manner of distributin them in the press string may be varie For instance, an

devices for kneading the obstacle in the formof a disk may be'attached directly to the s indle, so that it will a further subdivision and mixing of the "strings issuing from the sieve-like body will be efiected. I

I claim: M

1. In an apparatus. for manufacturing horn-like masses from casein, the combination of a casing formed with a bore, a screw operating in the bore, the threads of the screw being formed to compress the casein means for feeding casein to-the threads of the screw, a cooling jacket surrounding the y that arrangement casing and a portion of the bore to cool the casein while being fed forward, an extension on the casing havin a tapered bore which communicates with t e first mentioned bore a heatin chamber surrounding a part 01 the bore 111 the extension and a part of the screw whereby to heat the compressed casein. r

2. In an apparatus for manufacturing horn-like masses from casein, the c0mbination of a casin formed with a uniform bore,

a screw in the ore, the threads of the screw gradually decreasing toward one end, an

knead the casein, and means for heating the casein while same is bein kneaded. In testlmon whereof aflix my signature 20 in presence 0 two wltnesses. 1
